After a relative absence for many months, scrub ticks are making a come-back. Otherwise known as the paralysis tick, special medication is needed to protect pets from death and livestock can sometimes be killed. The effect of their poison is extremely debilitating quite apart from any allergic reactions, so this parasite should not be toyed with since it injects more poison with disturbance. They are best removed by freezing but if this is not available they should be removed as quickly as possible using a knife-blade against a thumb-nail. In hard-to-get-at-areas of the body, kerosene can be used to kill them.
